sUPPoR'r Foa Forms.

Application -led. December 23, 192,1. Serial No. 524,446'.

To all it 'may concern Be it known that I, WILLIAM E. WHrrE, a citizen'of the 'United States, and resident of Chicago, in the county of Cookand State oflllinois, have invented certain new and usefulV Improvementsin `a Support for Forms, of which the following ris a specification. f

' One-of thel objects of my invention is to providea simpleand/economical construction for use in concrete structures and byA meansof which less equipment is necessary for constructing a series ofoors'than by the use of any of the systems heretoforev su dgested.

n the device of my invention all of the parts except one insignificantelement can ybe disengaged and reused with the form ans before/thesupports can be removedy o this end I provide al plate or stirrupprovided with Vhooks lat its depending terminal portions and separatehangers adapted to be removably engaged with the hooks onthe stirrup.The hangers are provided with spaced apertures adapted to accommodatepins or nails and which serve as -the means of engagement of the hookedends of a telescopingV supporting bar. rI`he bar serves to support theform pans which rest on the support at their side edges.

My invention will be more readily understood by reference vto theaccompanying drawings, wherein,

Fig. 1 is a sectional view through a floor, slab and beams showing theapplication of my improvement thereto;

' Fig. 2 is an enlarged sectional view on the line 2 2 of Fig. 1, and

Fig. 3 is an enlarged transverse sectional view on the -line 3-3 of Fig.1.

In the drawings it will be seen that a Hoor slab 10 and beams 11 havebeen formed by employing a sheet metal form or so-called pan 12. Thelower surface of the beam is defined by a board or plank 13. The pansare supported at their marginal edges on a, horizontal teleseoping barconsisting of two channels 14, 15, interitted and held in properrelation by means of a pan 16. Located at a point near the ends of thebar are upstanding lugs 17, which serve to define the position of thesides of the band.

The ends of the bar are constituted by 'two strips. 18 of metal whichare held between the flanges of the channel 14 and suitably riveted in.place, the terminal 'portipns of the parts 18being spread apart` toystraddle-v a hanger 19. The hangeris provided with a plurallty ofvertically spaced horizontal apertures 20,v adapted to receive a. pin ornail 21, and the terminal portions 22 of the parts 18'are c'ut out toform' hooks adapted to engage the nail and to hold the bar in a desiredposition, as shown in Fig. 1. The hangers, of which two are provided ineach assembly, arepreferably of solid rectangular form and at the upperend are provided with a transverse fixed pin 23, which'engages with thehooked end 24 of a plate or. stirrup 25. This stirrup restsupon a joist26, which serves as the primaryv support for the plank 13, beneath thevbeam 11. The hangers are so. arranged that they may be disengaged fromthe stirrup after the supporting bar has been removed.v This enables thereuse of the' hangers together with the bars and form pans before thesupports are removed .from beneath the beams.

In practice the nails 21 are located ina predetermined aperture in thehangers, the. hangers then engaged with the stirrup and the supportingbar placed in its proper position. Thereafter the pans are lowered intoposition and the concrete poured. After it has become set to the desiredextent the 'nails 21 are knocked lout permitting the Vat its ends on thehangers of adjacent joists,

means permitting engagement of the ends of said support with the hangersat different oints in the length of the hangers, and

o-rm pans resting at their edges on said supports.

2. In a device of the class described, the combination of a supportingdevice, hangers carried thereby, a telescopic bar extending betweenadjacent supports, and means foi` disengageably connecting the ends ofsaid bar to said hangers at different elevations.

3. In a device of the class described, the combination of a supportingdevice, han ers carried thereby, a telescopic bar exten ing betweenyadjacent supports and having' hooked ends, and means for disengageablyconnecting the kends of said barv to said hangers at dierent elevations.

' 4f. vIn a device of the class described, the combination of aplateadapted to rest upon a joist, hangers depending from vthe plate, said`hangers being apertured, anl extensible bar having hooks atits ends, andpins adapted to enter the apertures in said hangers and to provide meansof engagement for the hooked ends of said bar.

5. ln a device'of'the dass described, the combination of a stlrrup,separable hangers provided wlth spaoed apart apertures adapted toacc'oinmodate ytransverse pins, a telescopio supporting bar 'the ends ofwhich are *shaped to engage the pins in said hangers and form pansadapted to rest at their edges on said bar.'
